The Common Bridge Transporter is an essential component of the Army's new Multi-Role Bridge Company (MRBC). The MRBC combines the roles of previous float and fixed bridge companies to perform their missions with less manpower and greater flexibility. In early 2003, the U.S. Army Program Manager for Bridging began fielding two new bridge systems to the MRBCs:
Both bridge systems are integral components of the MRBC’s objective capability. The Army designed MRBCs to give commanders a flexible and adaptable unit that can accomplish both float- and fixed-bridge missions. The MRBCs are 100 percent mobile -- every bridge load has a prime mover -- and take advantage of product standardization. The Army ordered 498 HEMTT M1977 Common Bridge Transporter (CBT) trucks in 2001 to upgrade the MRBCs as the trucks were delivered in 2002-2006. The 459th Engineer Company was the first unit in the Army to receive the CBT.
In April, 2015, the 36th Infantry Division was kind enough to display two of their M-1977's. The following pictures are a few of the ones I took at that event.
